04.01 Introduction

WinCC Web Navigator viiC79000-G8276-C522-01

Function Overview

The enormous growth of the Internet in recent years has had and is having a largeimpact on industrial development. One of the key factors responsible for theInternet boom was the development of the World Wide Web (WWW) Internetservice.

Browser applications with graphical user interfaces make accessing and navigatingthe Web easy: clicking a mouse button is all that is needed to cross geographicalborders.

The "WinCC Web Navigator" option package to the WinCC basic system (V5.0SP2 or higher) enables you to develop a solution for controlling and monitoringprocesses via the Intranet/Internet. With this option package and the standard toolsof WinCC, a new way of distributing the HMI functions of your plant - that employthe Intranet/Internet - can be implemented quickly and easily. The WinCC WebNavigator supports all current Internet security measures and provides Wizards tohelp you with the configuration.

The communication mechanisms used by the WinCC Web Navigator utilize apowerful and optimized event-driven transmission of data, which delivers the bestperformance via the Intranet/Internet.

The WinCC Web Navigator package consists of special WinCC Web NavigatorServer components that are installed on the server computer, and of WinCC WebNavigator Client components that are installed on the Intranet/Internet computer.

As a so-called "thin client", the WinCC Web Client can control and monitor arunning WinCC project from an opened Internet Browser, without the need ofhaving to install the complete WinCC basic system on the client computer.

The WinCC Web Navigator thus cost-effectively expands the networking of client-server systems to the Intranet/Internet. The project and the associated WinCCapplication are located on a server computer. Thus, there is a clear separationbetween the visualization component on the client computer and the runningWinCC project on the server computer. This makes it easy to set up OperatorStations for maintenance or diagnostic purposes.

Introduction 04.01

viii WinCC Web NavigatorC79000-G8276-C522-01

The WinCC Web Navigator Client software runs under Windows 98, Windows ME,Windows 2000 and Windows NT 4.0 or higher. The visualization takes place in anyInternet Browser that support the ActiveX technology by Microsoft such as theInternet Explorer 5.01 or higher.

The WinCC Web Navigator Client software can be installed in various ways: asusual via the CD-ROM or as a self-extracting file via the Intranet/Internet. In otherwords, when accessing the WinCC Web Navigator Server, it will be checkedwhether the client software has been installed. If the client software is missing, theuser will be asked to download the file to his computer and to perform theinstallation. This scenario provides the WinCC Web Navigator user with a highdegree of flexibility and mobility.

Another interesting and valuable aspect is the user-specific assignment of startpictures and languages. This assignment makes it possible to give different usersimmediate access to different areas of a project.

The pictures displayed on the WinCC Web Navigator Client can be controlled justlike in a normal WinCC system. In this way, the project running on the servercomputer can be influenced from any point on earth.

Security is an essential aspect when controlling and monitoring via the Internet.Thus, the WinCC Web Navigator supports all currently known security standards(used in the banking and insurance industry) ranging from user-specific logins andpasswords, firewalls, secure ID cards with PINs to RAS (Remote Access Service)and the SSL technology.

For the communication to its clients, the WinCC Web Navigator Server requires theMicrosoft Internet Information Server or the Personal Web Server that is integratedinto Windows 2000 or has to be installed from the supplied CD-ROM for WindowsNT. For setting up the WinCC Web Navigator Server, the WinCC Web Configuratoris provided, which makes the configuration easy and convenient for the user.

The Wizard is ideal for users without Internet server knowledge - after only a fewinputs, the Web Server is correctly configured.

In order for a WinCC project to run on the WinCC Web Navigator, its WinCCpictures have to be adapted and converted. As before, the WinCC pictures arecreated and edited with the WinCC Graphics Designer.

The Web View Publisher automatically makes the necessary changes to theproject data (conversion of WinCC pictures, scripts) so that they can run on theWinCC Web Navigator Client. In order to achieve the best possible performance,the Wizard limits itself to information that is necessary for the Web.

In connection with the "WinCC Guardian" option package, live video images can beshown via the Internet. The WinCC Guardian components are used to, amongother things, display live video images of your plant within WinCC pictures.

04.01 Introduction

WinCC Web Navigator ixC79000-G8276-C522-01

Upgrading of the WinCC Web Navigator V1.0 toV1.1

Web Navigator Server

At the server, the deinstallation of Version 1.0 is necessary.

Following that, Version 1.1 of the Web Navigator Server can be installed.

Web Navigator Client

At the client, the so-called "Zero Administration" exists: the Web server checks theversion compatibility between server and client and downloads the clientcomponent if necessary. This takes place when upgrading or downgrading.

• If a Web Navigator Client V1.0 meets a Web Navigator Server V1.1, Version1.1 will automatically be installed on the client.

• If a "new" Web Navigator Client V1.1 meets an "old" Web Navigator ServerV1.0, the communication will only operate with the functionality of Version 1.0.

In the first dialog box of the WinCC Web Configurator, you can specify whether anew standard Web site or a new virtual folder is to be created. The next step iscontingent on which option is selected.

• If you only operate the WinCC Web Navigator Web on your server, activate theoption "Create a new standard Web site (stand alone)"

• If the WinCC Web Navigator Web is to be added as a subfolder to your existingWeb, activate the option "Add to an existing Web (virtual folder)".



Editing the configuration

If the IIS/PWS has already been configured, you can use the WinCC WebConfigurator to change the settings of the existing Web server or of the virtualfolder.

Option "Add to an existing Web (virtual folder)"

Note

Included in the Appendix are the settings which are performed by the WinCC WebConfigurator.

If you accidentally delete the Web for the Web Navigator, restart your computerbefore creating a new Web with WinCC Web Configurator.

Please note, that when you perform manual changes to this Web and afterwardsyou are unable to communicate with your Web, the Web Configurator willautomatically attempt to correctly reset these settings.

If this method does not succeed, delete the Web from the IIS, reboot yourcomputer and use the Web Configurator to again create a new Web.

While operating the WinCC Web Navigator Server, only one Web project can beactive per computer, since the Web filter is loaded to the storage of the active Web.



3.2 Web Folder Setup

3.2.1 Creating a new Standard Web Site (stand-alone)

When selecting the "Create a new standard Web site (stand-alone)" radio-button,the following dialog box will be displayed.

Name of theWeb Site

Here you can specify a name for the Web site, e.g.WinCCWebSite.

Port Here you can specify the port that will be used by the httpprotocol for accessing the Internet.Only numbers ranging from 1 to 65535 may be entered.As a rule, the port numbers up to 1024 are reserved for thesystem. In this field, the http default port of 80 is set.

IP Address Each computer on the Internet possesses a unique address. Theaddress consists of a group of four numbers that are separatedby periods. The numbers can have values ranging from 0 to 255.The address is defined in the Windows Control Panel. You canonly use addresses that are shown in the list-box.

Via the IP address, you can specify whether the computer is tobe accessible on the Intranet or Internet or on both networks.For example, via the IP address x.x.x.x, the computer is knownto the Intranet, via the IP address y.y.y.y to the Internet. If youwant to make the computer only accessible on the Intranet orInternet, only select the corresponding address, e.g. for theIntranet, this would be x.x.x.x.

If the computer is to be accessible via the Intranet and theInternet, select "All not assigned".



Click on the "Finish" button to complete the configuration of the Server.

After finishing the configuration, the just created Web site (Web Navigator Web) isactive.

04.01 WinCC Web Navigator Security


4 WinCC Web Navigator Security

4.1 Overview

At present, when you connect your WinCC Web Navigator Server to anothercomputer, you are exposing your data to certain risks.

How the connection was established plays no roll, e.g. a connection via a localnetwork (LAN) or a dial-up connection via an Internet provider. Unauthorizedpersons could have access to your data. Your transmission could be intercepted,manipulated and misdirected. By providing certain directories in your system withspecial security layers, you can control the transmission of information.

There are several important concepts regarding a secure transaction:

Windows NT makes available powerful security functions which can be used tocheck users, for access checks and for monitoring purposes. The WinCC WebNavigator Server, which is based on the IIS, makes use of these Windows NTcapabilities to provide security for its Internet-based services. Windows NT uses asecurity model which manages the security for all services through the use of asingle registration process.

By creating user accounts and by setting up access authorizations for theseaccounts, the administrators can control which resources and services areavailable to the users. The central administration for the WinCC Web NavigatorServer is performed via the WinCC Web Administrator.

In addition, the WinCC Web Navigator Server supports firewall technology. Withthe help of a firewall, you can protect your system from unauthorized access.Firewalls require that the user must constantly identify himself. This identificationcan be performed with the aid of company-approved IP addresses, by using user-IDs and passwords - even secure ID cards and encrypted access passwords whichare changed at set intervals.

The most important components for the security of the WinCC WebNavigator Server are: Secure Socket Layer (SSL), secure HTTP (HTTPS),WinCC Web Administrator, firewall, secure ID card.

WinCC Web Navigator Security 04.01


4.2 SSL

SSL is a protocol which guarantees the data security between HTTP and TCP/IP.The standard for the security of WWW browsers and servers is defined by the W3C(World Wide Web Consortium). The W3C was established to create standardnormatives for the WWW. Additional information can be found in the Internet underhttp://www.w3c.org.

The SSL performs a security check before a TCP/IP connection is established.This check determines the security level on which the client and the server agreeand over it, the necessary authenticity operations for the connection are performed.

SSL performs the encryption and decryption of the data stream of the usedprotocol (e.g. HTTP = Hyper Text Transfer Protocol) as long as the connectionexists. All information, requests as well as responses, are encrypted. This includesthe information used for the authenticity check of the HTTP access (username/password) as well as all data transferred from the server to the client.

In order to use SSL, you require as system operator a certificate from a certificationprovider, e.g. VeriSign

Requests for a VeriSign certificate for the Microsoft Server can be found athttp://www.verisign.com.

4.3 HTTPS

HTTPS is an extension of the HTTP protocol. The SSL protocol is used to establisha secure connection between two computers, while HTTPS sends individualmessages securely. The communication between the WinCC Web NavigatorServer and Client is performed here using the HTTPS protocol.



4.4 WinCC Web Administrator

The WinCC Web Administrator allocates and controls access privileges for theusers of the Web site. This is achieved by assigning access privileges during usersetup

When a user logs into the system, the WinCC Web Navigator Server checkswhether the user is registered and whether the maximum number of WebNavigator Clients has been reached.

4.5 Secure ID Card

Remote Access Service (RAS) is a service which can be used, for example, to loginto a network directly from home. This is performed via the remotecommunications network. You are prompted to enter your card ID and PIN numberby the RAS server. The RAS server checks the entries and, if necessary, calls youback. This method ensures that only users with valid access information are able toaccess the server.



4.6 Firewall

4.6.1 General Information

A firewall is a system consisting of hardware and software that is installed at apoint between two networks and only lets authorized communication traffic passthrough. Improper actions are rejected and detected unauthorized use attemptscan be recorded. Thus, firewall systems are suitable to enforce defined rules withregard to security (security policy). Firewalls are often used when connecting to theInternet, protecting the internal network from the dangers of the Internet.

4.6.2 Principle of Operation

One computer with installed routing software and two interfaces (two networkadapters). The Internet is connected to one interface, the Intranet to the other.

This results in two different networks sharing one computer and providesexceptional security against attacks from the Internet.

4.6.3 Firewall Types

Among others, there are the following types of firewalls:

• Filter Firewall

• Proxy Server



Filter Firewall

A filter firewall controls the data stream based on a data package’s origin,destination, port and package type information. This information is contained inevery data package. Only selected network traffic can pass through the firewall.

Package filters are IT systems (Information Technology Systems) with specialsoftware that filter the information (IP packages) on the transport layer, i.e. theyeither let the information pass through or intercept it according to defined rules.The rules can operate by means of the source or target address as well as thesource or destination port that is typical for the respective Internet service. Manyrouters can also be employed as package filters. Unlike static package filters,dynamic package filters do not possess a defined set of rules, instead, the firewallmodifies the filter in response to certain events.

Proxy Server

Proxy servers permit indirect access to the Internet through the firewall. A proxy isan application for network services that is executed depending on thecommunication of the service and from system to system. The service program ofthe user does not communicate directly with the target system, but with the proxyserver of the firewall. The proxy evaluates the request and determines whether toestablish or deny the connection.

Proxy servers provide user authentication and integrity during the transfer of databetween client and server. The hypertext transfer protocol (http) proxy interceptsconnections from every Web Browser and directs the requests to the configuredWeb Server.

Proxy servers support content filtering. With content filtering, only certain contentsof HTML pages are permitted. In this case, the communication is rerouted via adefined port to an IP address such as the address of the WinCC server. If contentfiltering is active, the Web Navigator communication will no longer function. In thiscase, the use of SSL is recommended.

04.01 Establishing a Connection with the WinCC Web Navigator Server


5 Establishing a Connection with the WinCCWeb Navigator Server

Before you connect your WinCC Web Server to the intranet or Internet, you mustestablish a concept which takes into consideration relevant security and systemissues.

5.1 Island solution

In the figure shown above, the Web Clients are not connected to the intranet, butare rather used only to operate and observe the running WinCC project. You can,in this way, economically set up computer stations which can, for example, be usedfor monitoring or maintenance purposes.

Establishing a Connection with the WinCC Web Navigator Server 04.01


5.2 Navigator Server on the WinCC Server

The WinCC Server and the server components of the WinCC Web Navigator areinstalled on one computer. The WinCC Web Navigator client can be used tooperate and/or observe the running WinCC project over both the intranet and theInternet. A client/server system can be expanded through the use of WinCC WebNavigator Clients.

Firewalls are used to protect against attacks from the Internet. The first firewallprotects the WinCC Web Navigator Server from attacks originating in the Internet,the second firewall provides additional protection for the intranet.

04.01 Establishing a Connection with the WinCC Web Navigator Server


5.3 Separation of WinCC Server and WinCC Web NavigatorServer

Communication via a channel

The WinCC Server is assigned a group of automation devices. The project iscomposed of all data, including programs, configuration data and other settings.The WinCC project is mirrored 1:1 on the computer with the WinCC Server andWinCC Web Navigator Server and is not connected to the automation devices.

The data matching is performed via the OPC channel (OPC = OLE ProcessControl). The WinCC Web Navigator Server requires for this purpose a license forthe number of OPC tags.

Two firewalls are used here as well to protect the system from unauthorizedaccess. The first firewall protects the WinCC Web Navigator server from attacksoriginating in the Internet, the second firewall provides additional protection for theintranet.

Establishing a Connection with the WinCC Web Navigator Server 04.01


Communication via the process bus

As illustrated in the above picture, two firewalls are used to protect the system fromunauthorized access. The WinCC project is mirrored 1:1 on the computer with theWinCC Server and WinCC Web Navigator Server. The data matching is performedvia the process bus.

04.01 Configuration of the User Administration


8 Configuration of the User Administration

8.1 WinCC Web Administrator

The WinCC Web Administrator is used to give your Intranet/Internet users accessto your WinCC project and to assign user-specific start pictures and languages. Inaddition, user-specific rights for controlling and monitoring the process can beassigned. The WinCC Web Administrator allows you to quickly and easily set up asecure and clear Intranet/Internet user administration for WinCC.

If a user logs on to the system, the Web Navigator Server will check, whether theuser is registered and whether the maximum number of licensed Web NavigatorClients has been reached.

The tasks of the Web Navigator Administrator include:

• Creation and editing of users

• Assignment and administration of access rights

• Assignment and administration of start pictures and languages

The following access rights can be assigned to a Web Navigator Client:

None

The user rights assigned in the "User Administrator" editor will be evaluated for theuser. If no authorization has been assigned in the "User Administrator" editor, theuser will be able to perform this operation in runtime.

Unlimited Control and Monitoring (All)

The user is assigned the right to control and monitor the process in runtime.

04.01 Configuration of a Web Project


9 Configuration of a Web Project

9.1 Transfer of WinCC Pictures: Web View Publisher

To run your WinCC project on the Intranet/Internet, you can create pictures withstandard WinCC tools or use already created ones.

Note

Only use the WinCC Web View Publisher for projects that have been created withWinCC V 5.0 SP1 or higher.

Problems may occur with projects that have been converted from WinCC V4.02and V4.02 SP1 to WinCC V5.0 SP1 / SP2.

Please read the corresponding chapters with regard to limitations, when usingcomplex functions or scripts. If the project and the pictures were created with theWinCC Graphics Designer, a Wizard is available to make the pictures run on theInternet.

The Web View Publisher automatically makes the necessary changes to theproject data (conversion of WinCC pictures, scripts) so that they can run on theWinCC Web Navigator Client via the Intranet/Internet.

The following conversions will be performed:

• Compression of the data to achieve the best possible performance on theInternet

• Removal of project-specific data that is unnecessary for the operation

• Conversion of picture windows into ActiveX components

• Conversion of scripts so that they can run on the WinCC Web Navigator Client

How to start the Web View Publisher:

1. In the project navigation window of the WinCC Explorer, right-click on the "WebNavigator" entry.

2. In the pop-up menu displayed, click on the "Web View Publisher" menucommand.

Configuration of a Web Project 04.01


Web View Publishing Wizard

1. The Wizard opens with the following introductory dialog box.

2. Click on the "Next" button to go to the next dialog box.



3. In the dialog box, select the folder in which the pictures of WinCC arelocated, e.g. "...\Siemens\WinCC\WinCCProjects\GraCS", and the folder inwhich the converted pictures are to be stored. For the runtime of the WebNavigator, the suggested default folder within the WinCC project folder has tobe kept as the storage folder for the converted pictures. The path should onlybe changed, if pictures are to be transferred, for example, to another project.

4. Click on the "Next" button.

5. In the following dialog box, select the pictures that are to be published on theWinCC Web Navigator Server.




7. Use the "" button to select the project functions that are to be published.


9. Set the check-boxes. "Check Scripts" activates the conversion of scripts sothat they can run on the client. If "Referenced Graphics" is activated,graphics (e.g. bitmaps) referenced in the pictures (*.PDL) will be transferredas well.



10. Click on the "Finish" button to start the conversion of the pictures. Theprogress bar will indicate the progress of the conversion.

11. After the completion of the conversion, a dialog box will be displayed.Acknowledge this dialog box to exit the operation.



9.2 Transfer, Adaptation of existing Projects

You can use already existing projects that have been created with WinCC andmake the accessible via the Internet or Intranet.

Essentially, this requires the conversion of the already created WinCC pictures withthe WinCC Web View Publisher into the WinCC Web folder and the setup of theWeb users with the WinCC Web Administrator.

Note

Only use the WinCC Web View Publisher for projects that have been created withWinCC V 5.0 SP1 or higher.

Problems may occur with projects that have been converted from WinCC V4.02and V4.02 SP1 to WinCC V5.0 SP1 / SP2.

Version 1.1 of the WinCC Web Navigator has some functionality limitations and asa "thin client" solution does not support all functions that are offered by thestandard WinCC basic system.

Thus, check your existing WinCC configuration with regard to the following pointsand limitations, and adapt it if necessary.

If scripts are used in pictures, objects addressed by scripts must not contain blankspaces or special characters in their names.

For example: The object named "Button 1" is to change its background color, if acertain value changes. If this is implemented via a script, the object name must bechanged from "Button 1" to "Button1" (no blank space). The reason for this is thatthe script interpreter software used by the Web Navigator Client does not supportblank spaces and special characters in object names.

Warning

In V1.1 of the WinCC Web Navigator, the available functions and standardfunctions that can be used on the WinCC Web Navigator Client are limited toapproximately 600. A list of functions supported/not supported by the WinCC WebNavigator Client can be found in the appendix.



9.3 Limitations

When transferring the comprehensive WinCC runtime functionality to the minimalruntime environment of the WinCC Web Navigator Client, limitations areunavoidable.

Among others, the following WinCC options or functions are not available on theWinCC Web Navigator V1.1 via the Intranet/Internet:

• The WinCC Web Navigator Client only offers the view of a running WinCCproject. A configuration of the WinCC Server projects via the Web Client is notpossible.

• Only those WinCC option packages/add-ons can run on the WinCC WebNavigator, whose documentation expressly states that.

• ODK functions are not supported on the WinCC Web Navigator Client. A list offunctions supported/not supported by the WinCC Web Navigator Client can befound in the appendix.

• The PCS7 options do not support the current version of the WinCC WebNavigator Client.

• The WinCC Report Designer is an integrated reporting system for the time- orevent-triggered documentation of alarm messages, operations and archivecontents. The reporting system is not supported via the Intranet/Internet. Thus,the output of reports is not possible on the Web Client.

• WinCC User Archives are not available via the Intranet/Internet.

• Operator messages are not supported by the current version of the WinCCWeb Navigator Client.

• No separate archive system is running on the WinCC Web Navigator Client.The message archive or message system can only be controlled andmonitored.

• If scripts are used in pictures, objects addressed by scripts must not containblank spaces or special characters in their names. This is especially importantfor projects that have been converted from WinCC V4.02 and V4.02 SP1 toWinCC V5.0 SP1 /SP2. The following special character in object names issupported: "_". The object name "Tank 1" must be changed to "Tank_1"("_Tank1" needs not to be changed, "Tank.1" is not supported).

• The indirect addressing of tags is not supported.

• Global Scripts running locally on the client are not supported. Global Scriptsrunning on the server are supported.

• The redundancy switch is not supported.

When using functions that are not supported, the user will be informed about this inruntime via clear text messages.



9.4 Using Scripts

Global Script

The WinCC Web Navigator Client only provides a view to the project. Theconfiguration of scripts takes place in the server project of the WinCC server. Forthis reason, the "Global Script" editor is not offered on the WinCC Web Navigator.

Unlike in WinCC, all scripts on the WinCC Web Navigator Client are integrated inthe same name space. This makes possible function calls between scripts that areimplemented in different objects. Global tags are known to all scripts. For thisreason, "defines" - such as "#define Motor 1 100" - that are stored in scripts of thisfile may only occur once across all scripts.

If multiple occurrences are required due to configuration reasons, "define" needs tobe deactivated first by a "#undef".

Example:

#undef Motor1

#define Motor1 200

Actions

Actions are scripts that respond to operations and events. The appendix of theOnline Help contains the functions that are supported.

Warning

Since the CISS compiler used for the interpretation of scripts/functions in picturesis conforming to ANSI-C, no anonymous structures and unions are used. In theVARIANT2 structure compatible to VARIANT, the stored union is named "vdata".

VARIANT2 vTest;

VariantInit((VARIANT*) &vTest);

vTest.vt=VT_I4;

vTest.vdata.lVal=1024;

VariantClear((VARIANT*) &vTest);

The names of objects used in WinCC pictures and addressed by scripts must notcontain blank spaces or special characters. Also, object names are case-sensitive.



9.5 The "PdlPad" Tool

Installing the WinCC Web Navigator Server will also install the "PdlPad" tool, whichcan be accessed from the Windows start menu underSIMATIC\WinCC\WebNavigator\Server\Bin.

The Web View Publisher automatically made the necessary changes to yourpictures so that they can run on the WinCC Web Navigator Client via theIntranet/Internet. These pictures can be found in the WinCC project path under...\WebNavigator\Pictures. Please also see the "WebNavigator.CHM" chapter ofthe documentation under "Transfer of WinCC Pictures: Web View Publisher" .With the help of the "PdlPad" tool, the scripts used in the pictures can be checked.To do so, open the WinCC picture in the PdlPad and click on the "Check Scripts"icon.



9.6 Differences to the WinCC Base System

9.6.1 Script Execution

Contrary to the WinCC base system, event-triggered scripts (OnClick, etc.) areexecuted in the same process space as the picture display, namely in the contextof the Internet Explorer.

Consider this, when working with delays in scripts (e.g. Sleep(3000)). In this case,the displayed picture will not be operational for the time period set.

9.6.2 Opening a Picture

The Web Navigator downloads a WinCC picture from the Internet in anasynchronous manner. Because of this, a picture change is not performedsynchronously as in the base system, but asynchronously. This fact has to beconsidered in scripts that trigger a picture change.

The following applies:

If a picture window is selected within a script, then the same script will not be ableto access the objects of the new picture, since the picture is not yet loaded at thetime. In this case, a delay (e.g. Sleep(2000)) will not help either, since the scriptand with it the Internet Explorer as well are waiting.

A better solution is to execute the subsequent script sections at the "OpenPicture"event, which is triggered once the picture has been loaded.

9.6.3 Scripting

Preprocessor Definition:

Especially for the Web Navigator, the scripting possesses a preprocessordefinition:

RUN_ON_WEBNAVIGATOR

The code that follows this preprocessor definition will be executed by the WebNavigator. Thus, it is possible to write scripts that behave differently under the WebNavigator than under the base system.



Example:

void OnOpenPicture (char* lpszPictureName, char*lpszObjectName, char* lpszPropertyName)

{

#ifdef RUN_ON_WEBNAVIGATOR

// add the code applying to the Web Navigator only

}

#else

// add the code applying to the base system only

#endif

}

9.6.4 Addressing of Objects in other Pictures

If the objects of a picture are to be accessed from another picture via a script (e.g.objects in a parent picture or a picture window), this can only be achieved byemploying relative addressing (unlike in the base system).

All C-script functions that access the objects of a picture, request the picture nameas the first parameter.

For example: SetPropChar ("Start Picture", "Text1", "Text","Hello, here is a text");

When accessing objects that are not located in the same picture, the WebNavigator provides specially defined picture names that specify the addressing ofthe pictures relative to the current picture.

Addressing of an Object in the Basic Picture

If there is no ambiguity, specifying the picture name suffices (just like in the basesystem):

SetPropChar ("Start Picture", "Text1", "Text", "Hello, hereis a text");

Otherwise, the addressing can be performed independent of the picture nameeither with an empty string or lpszPictureName = "/".

Example:

SetPropChar ("", "Text1", "Text", "Hello, here is a text");

or

SetPropChar ("/", "Text1", "Text", "Hello, here is a text");



Addressing of an Object in the Parent Picture

If there is no ambiguity, specifying the parent picture name suffices (just like in thebase system):

SetPropChar ("Picture1", "Text1", "Text", "Hello, here is atext");

Otherwise, the addressing can be performed independent of the picture name withlpszPictureName = "../".

Example:

SetPropChar ("../", "Text1", "Text", "Hello, here is atext");

Picture in a Picture Window

If the object to be addressed is located in the picture of a picture window ("PictureWindow1"), it can be addressed relative to the current picture as follows:

SetPropChar ("./Picture Window1", "Text1", "Text", "Hello,here is a text");

or, if the Picture Window1 is located in the parent picture:

SetPropChar ("../Picture Window1", "Text1", "Text", "Hello,here is a text");

or, if the Picture Window1 is located in the basic picture:

SetPropChar ("/Picture Window1", "Text1", "Text", "Hello,here is a text");

9.6.5 Synchronous Script Functions

Exercise caution when dealing with synchronous script functions such as"SetTagCharStateWait" that synchronously write a tag and then wait for the result.Since these calls go to the server in a synchronous manner, frequently callingthese script functions negatively impacts the performance of the client. Through anInternet connection, such a call may even take several seconds.

Script functions that manipulate objects in the displayed picture are safe, since around trip to the server does not take place.



9.6.6 Defining Script Tags local to a Picture

To store picture-specific data in scripts, you should refrain from using datamanager tags in the Web Navigator. These tags - when read or written in scripts -always cause a round trip to the server, which is costly in the Internet.

There are several ways to store picture-specific data:

Configuring "invisible" Graphic Objects

By creating invisible graphic objects, you will be able to use the properties of theseinvisible objects as picture-specific tags.

An additional advantage is that actions can be performed upon the change of thesestored values.

Example:

Creation of an invisible Text Field

In this case, any text can be conveniently stored in the text property, which canthen be read or written to by any script handler.

In the color properties of the text field, for example, colors can be stored, which areread or written to by scripts and thus can influence the status of the picture withoutrequiring a round trip to the server.

04.01 Using the WinCC Web Navigator Client


10 Using the WinCC Web Navigator Client

With the WinCC Web Navigator Client, a WinCC project which is running on theWinCC Server can be viewed, operated and observed. For this reason, it is notpossible to configure the server project

The following functions are available on the WinCC Web Navigator Client:

Displaying WinCC pictures over the intra-/Internet

The Graphics Designer is used to create process images in WinCC. The Web ViewPublisher automatically performs the necessary adaptation of the project data(conversion of WinCC pictures, scripts). The pictures are then capable of runningin the WinCC Web Navigator Client.

The communication between the WinCC Web Navigator Server and Client ispossible here using the HTTPS protocol. In order to protect the system fromunauthorized access, HTTPS should be used.

Accessing Process Tags

Process Tags can be read and written as in WinCC. The process image is suppliedwith tag values via the WinCC Explorer. Depending on the user’s access privilegesin the WinCC Web Administrator, he can either observe or both operate andobserve.

Displaying messages

The existing WinCC message archive and/or message system of the WinCCServer can be operated and observed on the WinCC Web Navigator Client via theWinCC Alarm Control. It is not possible to execute the "Loop in Alarm" function.

Displaying process values in trends and tables

It is possible to display the process values in trends and tables via the WinCCOnline Trend Control and WinCC Online Table Control from the WinCC WebNavigator Client. Changes, with regard to the Trend and Table windows, arepossible. It is, however, not possible to configure an individual archive on the WebNavigator Client as the process value data come exclusively from the archivesystem on the WinCC Server.

Using the WinCC Web Navigator Client 04.01


Language switch

It is possible to switch languages on the WinCC Web Navigator Client as well.

If a text from the text library is changed on the WinCC Server while in runtime, itmay, under certain circumstances, not automatically be detected by the WinCCWeb Navigator Client. The Internet Explorer stores the pictures in its cache. Thecache is a special memory area in which the contents of frequently used objects,e.g. Internet pages, are stored. In order to update the displayed pictures, thepicture must be reloaded by using the Reload icon.

In order to show streaming video images, the WinCC Web Navigator Clientrequires the Camera Viewer setup of the WinCC Guardian to be run.

WinCC Web Navigator and WinCC Guardian 04.01


04.01 Using the Terminal Services for the WinCC Web Navigator


14 Using the Terminal Services for the WinCCWeb Navigator

Introduction

The terminal services of Windows 2000 Server give multiple thin clients access tothe desktop of a Windows 2000 server. On the server, various applications such asWinCC are run. With the terminal services, only the user interface of the applicationis transmitted to the clients. Each client’s keyboard inputs and mouse operationsare returned back to the server.

The advantages of this method include:

• Using a robust hardware for the clients, without fan or harddisk, e.g. in dustyenvironment.

• Using mobile clients with limited power supply (Handhelds, Palmtops).

• All applications are running on the server in a save environment.

• Easier and more centralized administration and system maintenance.

• Support of different operating systems (e.g. Windows CE, Linux, Windows 3.1).

Web Navigator Client V1.1 is released for Windows 2000 Terminal Services with amaximum of 25 sessions each terminal server.

The Web Navigator Client is build in a "THIN²"-structure. That means, that theapplication, which is multiple executed on the terminal server (e.g. Web Navigator)is "thin" with respect to demands for the hardware.

Using the Terminal Services for the WinCC Web Navigator 04.01


Terminal services are performed on the server in two modes:

• In the application server mode, the terminal services are used to forwardWindows programs and the desktop to a network server. In this case, theterminal services can also transmit desktop applications to computers thatnormally do not run Windows.

• In the remote administration mode, the terminal services allow a server to bemanaged from any location on the network.



14.1 Requirements for Using the Terminal Services

This chapter outlines the hardware, software and operating system requirementsfor using the terminal services and the WinCC Web Navigator.

Terminal Server

OperatingSystem/Software:

Windows 2000 ServerApplications that are to be carried out on the clientshave to be callable and executable in multiple instances.


min. 700 Mhz Pentium III256 MB RAM plus additional RAM for each clientThe processor and memory requirements grow linearly,i.e. when using twice the number of clients, the numberof processors (max. 4) and the amount of memory(approx. 40 MB per client) need to be doubled as well.

Other: If many users access the server, a high-performancenetwork card should be employed.ISA bus systems should not be used, but instead EIDEor PCI.

Terminal Services Clients

Client minimumRequirements:

Network Card with TCP/IPTerminal Client RDP 5.0Display/MonitorPointing Device

Recommended for use as clients are MOBIC T8 (Industrial Handheld) or MP370Thin Client (12" TFT Touch Panel).

Note

For clients not running on Windows 2000 computers, the Terminal Client Accesslicenses by Microsoft are required. Additional information pertaining to terminalclient licensing can be found under://www.microsoft.com/GERMANY/ms/serversuiten/lizenzierung/w2k_tsfaq.htm



14.2 Terminal Services Setup

In the following chapters, the setup of the terminal services for a simple example inconnection with the WinCC Web Navigator Client is shown.

1. Activation of the terminal services (terminal services server).

2. Installation of the application, e.g. WinCC Web Navigator Client (terminalservices server). This point will not be described. Information pertaining to theinstallation can be found in the corresponding documentation and the OnlineHelp.

3. Creation of the client data carrier (terminal services server).

4. User setup for the access via the terminal services (terminal services server).

5. Installation of a client (client computer).

6. Configuration of the terminal services connections (client computer).

7. Start of the application on the client.

Additional information can be found under "Terminal Services" in the Online Help ofWindows 2000 Server.



14.2.1 Activation of the Terminal Services on Windows 2000 Server

The terminal services can be activated in two different modes.

1. Remote Administration Mode: In this mode, the terminal services allow aremote access to a server from any location on the network. In this mode, theprograms to be used can be installed before or after activating the terminalservices. The terminal services licensing needs not to be activated.

2. Application Server Mode: In this mode, Windows programs can be distributedsafely and effectively using a network server. The programs to be used withthe terminal services should be installed after activating the terminal services,since the terminal services register these programs for multi-user access andprovide improved management.

For this example, the application server mode is required, which is activated asfollows:

• Insert the "Windows 2000 Server" CD-ROM into the CD-ROM drive of theserver.


• In the "Add/Remove Programs" dialog box, click on the "Add/Remove WindowsComponents" icon. The "Windows Components Wizard" dialog box will open.

15 Appendix

15.1 Internet Information Server

15.1.1 An overview of the highlights

• Optimized system availability through failure safety (24/7/365)

• Transacted Active Server Pages (ASP) ensure that processes running inparallel do not mutually interfere with one another. Script debugging simplifiesthe development of such applications

• Flexible configuration

• Low operating costs through optimized administration tools

• Ensured compatibility through strict adherence to common Internet standards

• Secure information exchange through effective encryption mechanisms

• Individually configurable search functionality

15.1.2 Reliability

Reliability is a key term in modern IT management. It is one of the fundamentalrequirements for successful implementation of IT technologies. The possibility tointegrate the Microsoft Transaction Servers into the Microsoft Internet InformationServer 4.0 makes the Windows NT Server the most comprehensive platform for thedevelopment and expansion of dependable and simultaneously scalable Webapplications. The Transaction Server ensures very efficient processing of all datastreams between server and back-end system in a client/server environment.

The Microsoft Internet Information Server guarantees stability through 3 key points:

• System security: Various applications can run simultaneously on the WebServer. If applications from third parties (or even "homemade" applications) arebeing run, they may cause problems through incompatibility and may evenresult in a system crash. The Internet Information Server makes certain thatsuch events affect neither other applications nor the system as a whole. If oneof the described applications should crash, it is exited and, if necessary,restarted.

• Transacted Active Server Pages: This new development allows thedeveloper to design applications which can simultaneously perform multipleactions. These actions can work towards a common cause or run entirelyindependently from one another. In any event, it is ensured that they do notinterfere with one another and cause instability in the system operation. Inparticular, this can play a role in database applications.

• Script debugging: A special function which makes the programming ofapplications using Active Server Pages easier for the developer.

Appendix 04.01


15.1.3 Settings on the Internet Information Server

In the next dialog box, only activate the "Allow Read Access" and "Allow ScriptAccess" check-boxes and exit the Wizard by clicking on the "Finish" button.

04.01 Appendix


15.1.4.2 Virtual Folder

If your Web site includes files which are either not on the same drive as the rootdirectory or are not on the same computer and are to be executed on the InternetInformation Server, you must create a virtual folder to accommodate these files inyour Web site. Such a folder can be located on a local drive or on anothercomputer in the network. If you would like to use a folder on another computer, youneed to specify the UNC name (UNC = Universal Naming Convention) of the folderand provide a user name and password for access authorization. An overview of allvirtual folders can be found under Virtual Folders.

How to Create a Virtual Folder

1. In the Internet Services Manager, select the Web site which you would like toadd to the folder.

2. Click on the Action button, point to New and then select Virtual Folder.

3. Make the actual settings for new virtual folders with the help of the wizard.

Appendix 04.01


15.1.5 Setting the Start Page

The start page is the document which is opened on a browser request for data.The default page names are "index.html, index.htm, default.html, default.htm"

• In the Internet Services Manager, click the right mouse button on the name ofthe Web site, e.g. WinCCWebsite, and in the pop-up menu click on the"Properties" entry

• Click on the "Documents" tab and insert "webclient.asp" as the defaultdocument. In this case, Webclient.asp is called up on a browser request andthe respective start picture displayed in the browser.

An ISAPI filter is a program which reacts to events which occur during theprocessing of an HTTP request.

• In the Properties dialog box of the "WinCCWebsite" Web site, click on theISAPI Filters tab.

• This table lists the states, names and priority levels of the filter.

• Click on "Add" to activate the filter of the Web Navigator (Webfilter.dll). Theprogram is located in the installation folder(..\Siemens\WinCC\WebNavigator\Server\Web\bin\..) of the WinCC WebNavigator.

• If the ISAPI filter has been changed (deleted and then relinked), the PC mustbe restarted or, as the case may be, the WWW Publishing Service must beexited and restarted.

Note

While operating the WinCC Web Navigator Server, only one Web project can beactive per computer, since the Web filter is loaded to the storage of the active Web.

Appendix 04.01


15.1.7 Setting the Default Authentication

• In the Properties dialog box of the "WinCCWebsite", click on the "DirectorySecurity" tab. The security functions of the Web Server are set in this tab.

• In the "Enable anonymous access and edit the authentication methods for thisresource" entry, click on the "Edit" button.

Activate "Basic Authentication (Password is Sent in Clear Text)". This is acommonly used method for identifying and authenticating the user in accordancewith the industry standard.

15.2 Troubleshooting and Error Correction

No Communication between the WinCC Web Navigator Server and the Client

If "Content Filtering" is set for an Internet connection from a provider (participatingproxy, firewall), the Web Navigator communication will no longer function. Withcontent filtering, only certain contents of HTML pages can be displayed. In thiscase, the communication is routed via a defined port to an IP address such as theaddress of the WinCC server.

• At the WinCC Web Navigator Server, its IP address must deactivate the "SmartFiltering". Filtering also makes no sense, since no viruses or HTML contentsare present on the WinCC server.

• The WinCC Web Navigator Server changes the principle of the communication- the client calls in a defined interval via the registered tags.

• If the customer uses the SSL technology, the "Content Smart Filtering" is notpossible, since the data is transmitted encrypted.

Connection Termination

In the case of connection terminations, delays or communication fluctuations -which occur intermittently in the Internet environment - it may happen that theconnection to the WinCC Web Server gets severed. In that case, the followingdialog box would be displayed.

Click on the "Yes" button to reestablish the connection and to update the picture.

04.01 Appendix


No pictures are being displayed

In the Internet Explorer, check whether the following setting has been activated:

• Internet Explorer 4.0: Menu commands "View"/"Internet Options", tab:"Advanced"/"Browse in a new process"

• Internet Explorer 5: Menu commands "Tools"/"Internet Options", tab:"Advanced"/"Open Browser window in a new process" (provided that the optionis available)

On the WinCC Web Navigator Server computer, check whether the correct Website has been activated. Additional information can be found in the "Checking theactivated Web Site" chapter.

Incorrect Start Picture

The start picture displayed by the Internet Explorer does not match the picture youhave just edited.

• Start the Web View Publisher to make the new picture available to the Internet.

• Delete the temporary Internet files. Internet Explorer 4.0: under "View"/"InternetOptions"; Internet Explorer 5.0: under "Tools"/"Internet Options".
